STOVEPIPE.

sPncIFmATIoN forming part of Letters Patent No. 661,824, dated November13, 1900.

Application filed August 18, 1900. $erial No. 27,341. (No model.)

To all whom it may 00711067711:

Be it known that I, FRANK L. SMITH, a citizen of the United States,residing at Marietta, in the county ofMarshall and State of Kansas, haveinvented a new and useful Stovepipe, of which the following is aspecification.

This invention relates to stovepipes, and has for one object to provideimproved means for adjustably connecting Stovepipe-sections and tofasten them together to prevent accidental separation thereof, while atthe same time permitting of the sections being disconnected to take downa pipe-line.

It is furthermore designed to adapt the present device for applicationto ordinary stovepipes now in common use without mate rial-1y alteringthe same beyond the provision of an opening in one end thereof.

.With these and other objects in View the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanyingdrawin gs, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claimswithout departing from the spirit or sacrificing anyof the advantages of the invention. i In the drawings, Figure 1 is anelevation of adjacent stovepipesections connected by means of thepresentinvention. Fig. 2 is an enlarged detail transverse sectional viewtaken on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view ofa portion of one end of a stovepipe provided with an opening'inaccordance with the present invention. Fig. 4 is a plan view of atongued strip used in fastening the Stovepipe-sections. Fig. 5 is adetail perspective view of a fastening-clip similar tothe tongued stripand which is deopposite edges of the sheet from'which the stove-pipe ismade. At one end of the stovepipe and at one side of the joint thereofthere is provided a slot or opening 2, which extends longitudinally ofthe Stovepipe, and an intermediate transverse slot or notch 3 intersectsthat edge of the slot 2 which is farther away from the stovepipejoint,as best shown in Fig. 2 of the drawings. These two slots result in asubstantially T-shaped slot arranged transversely of the Stovepipe andadjacent to the joint thereof.

The stovepipe is furthermore provided with a tongued metallic strip 4,having spaced lateral tongues 5, as shown in Fig. 4, or adjacenttongues, which are separated from each other by means of lateralincisions, as shown in Fig. 1. The flat body portion or rear edge ofthis strip is folded with the'joint in; the

original manufacture so as to fixedly connect I the strip therewith,with the tongues projecting laterallyoutward through the lateral edge ofthe joint, as shown in'Fig. 2 of the drawings. It will of course beunderstood that the tongues are originally pressed flat against theouter sideof the stovepipe, so that the latter maybe free ofprojections; also, thestrip terminates at one end adjacent to theopening 2, while its opposite end extends to the opposite end of theStovepipe-section. Moreover, the strip and the opening are 10- catedupon opposite sides of the joint.

In connecting the stovepipe-sections the end of the tongued, section isinserted into the adjacent end of the other section, after whichthesections are twisted or turned in so as to enter one of the tongues intothe open ing 2, as indicated at the bottom of Fig. 1,

thereby interlocking the stovepipes against accidentaldisplacement, butat the same time permitting of the sections being separated by a reverseturning thereof. Should the tongue not readilyenter the opening or slot,any suitable pointed instrument may be inserted through the transverseslot or notch 3, so as to enter under the free end of the tongue,whereby the latter may be pried or forced away from the adjacent pipeand directed into the opening in the other pipe. It will be understoodthat each pipe-section is designed to have an opening at one end and atongued strip extending from the opening to the opposite end of thepipe, so that any one of the tongues of the adjacent pipe 'may beinserted into the opening of the other pipe, whereby the sections mayhave a longitudinal adjustment for the entire length of the sections. 5

Any ordinary Stovepipe may be provided with the present invention bymaking the T- s'haped opening in one end thereof and inserting a shorttongued strip or clip 6 into the joint of the pipe at the opposite. endthereof,

A stovepipe-seotion, having an external lateral tongue at one end, and acorresponding longitudinal slot. at the opposite end of the Stovepipe,one edge of the slot having a lateral notch.

3. A Stovepipe-section, having a longitudinal folded joint, a slot atone end of the pipe, and a tongued strip, having its back edge foldedinto the joint, with the tongues extending laterally therefrom and uponthe exterior of the pipe, the tongues and the slot being upon oppositesides of the joint.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

FRANK L. SMITH.
